Star magazine (we told you it's a rumor) claims that Jenner has a "history of cheating and stealing." Not only does the magazine write that Jenner is "hiding money from her estranged hubby [Bruce Jenner]," but the tabloid goes on to say that Jenner actually cheated on her former fiancé, professional golfer Cesar Sanudo, with Simpson.

There's a hint of credibility to this recent accusation of Jenner cheating because Star actually spoke with Sanudo's family. Says Star, "Fresh out of high school, Kris got engaged to professional golfer Cesar Sanudo, and his family has opened up to us exclusively with claims about her cheating and stealing way back then."

Jenner and Sanudo began dating in 1979 and his family says Jenner was instantly drawn to fame. "Cesar introduced her to a lot of showbiz big shots, and he'd take her to big parties at mansions and on yachts," said Carlos Sanudo, Cesar's brother. "In fact, you could say that Kris would never have made her family as big as it is today without the connections Cesar began making for her years ago."

Just how low did Jenner go in her relationship? Sanudo says she even flirted with him when Cesar wasn't looking. "Whenever a bunch of us would be partying over at Cesar's condo while he was out on the road, Kris would hit on any number of guys," he revealed. "She even made a move on me!"

OK, so Jenner isn't exactly winning any points for morals and ethics, but what did Sanudo have to say about her alleged affair with Simpson?

"One night, my phone rang at 2:00 a.m., and it was Cesar," explained Sanudo. "He was on the road at a tournament, and he told me he'd been calling Kris all night at his condo with no answer." Carlos elaborated, "Then he said 'I think Kris is screwing O.J. over there! I know she's got something going on with him, and I need you to take the key to my condo and go over there!'"

Sanudo told Star he declined to ambush Jenner, telling the tabloid, "I could have been O.J.'s first victim!"

Jenner has yet to comment on the story that she had an affair with O.J. Simpson. However, Kris did confirm she cheated on her late husband, Robert Kardashian, with Todd Waterman in her September 2011 memoir, Kris Jenner… And All Things Kardashian.

There are also multiple reports Kris cheated on Bruce with Waterman again. Karen Jenner, Bruce's sister, says Kris confessed to being unfaithful. "Kris has admitted to cheating," said Karen. "It's so funny because I could never see a guy cheating on her. She's so powerful."
